Study Notes

Reproductive Systems

  • Female Reproductive Organs:
    • Ovary: Produces eggs and sex hormones.
    • Oviduct (Fallopian Tube): Conducts eggs toward the uterus.
    • Uterus: Houses the developing fetus.
    • Vagina: Receives the penis during copulation and serves as the birth canal.
  • Male Reproductive Organs:
    • Testis: Produces sperm and sex hormones.
    • Epididymis: Stores maturing sperm.
    • Vas deferens: Conducts and stores sperm.
    • Seminal vesicle: Contributes secretions to semen.
    • Prostate gland: Contributes secretions to semen.
    • Bulbourethral glands: Contributes secretions to semen.
    • Urethra: Conducts sperm.
    • Penis: Organ of copulation.

Sensory Systems

  • Hearing: Hair cells vibrate, transmitting auditory information to the temporal lobe.
  • Vision:
    • Rods: Process black and white light.
    • Cones: Process color light.
    • Rods and cones work together to process visual information transmitted to the occipital lobe.

Excretory System

  • Kidneys: Produce urine, regulating blood volume and composition.
  • Ureter: Transports urine from kidneys to the bladder.

Solutions

  • Isotonic: Solute concentration identical to the cell, no net movement.
  • Hypertonic: Solute concentration higher than the cell, water moves out.
  • Hypotonic: Solute concentration lower than the cell, water moves in.
  • Osmosis/diffusion: Movement from high to low concentration, no energy required.

Cell Types

  • Prokaryotic: Bacteria and Archaea; lack membrane-bound organelles, have a localized nucleoid region.
  • Eukaryotic: All other cells; have membrane-bound organelles, a nucleus.
